What are the advantages and disadvantages of polymer batteries
A polymer battery is a polymer lithium-ion battery, which is a type of lithium-ion battery, a polymer lithium-ion battery. Let's summarize the advantages of a polymer lithium-ion battery:
(1) The capacity density is large, and its capacity density is 1.5~2.5 times that of nickel-metal hydride batteries or nickel-cadmium batteries, or higher;
(2) The self-discharge is small, and its capacity loss is also small after being placed for a long time;
(3) Long service life, the cycle life of normal use can reach more than 500 times;
The disadvantages of polymer lithium-ion batteries are:
1. The cost of the battery is high, and the purification of the electrolyte system is difficult.
2. To protect the circuit control, overcharge or overdischarge will destroy the reversibility of the chemical substances inside the battery, which will seriously affect the life of the battery.
